Clinical trials

The goal of this clinical trial is to explore the impact of anxiety/depression on the efficacy of asthma controller medications and to develop a risk prediction model for asthma acute exacerbations in patients with asthma. It will also analyze the association between anxiety/depression severity and asthma severity. The main questions it aims to answer are: Does anxiety/depression affect the therapeutic effect of asthma controller medications (e.g., asthma control level)? Can a reliable risk prediction model for asthma acute exacerbations be established based on anxiety/depression and other relevant factors? Researchers will conduct a prospective observational study to collect and analyze data from participants, without additional interventions beyond standard clinical care, to explore the above research questions. Participants will: Complete baseline assessments, including demographic information collection, medical history review, lung function tests, anxiety/depression evaluations (via GAD-7 and PHQ-9 scales), and provide biological samples (induced sputum, feces, blood) Undergo follow-up visits at 3, 6, 12, 18, and 24 months after baseline Report asthma symptoms, acute exacerbation events, and cooperate with required clinical checkups during follow-up

Inguinal hernia is one of the most common conditions in general surgery. In clinical practice, surgeons frequently face a dilemma: during the evaluation of a patient with unilateral symptomatic inguinal hernia, a contralateral asymptomatic defect is discovered-either preoperatively on physical examination or intraoperatively during laparoscopy. The question then becomes: how should this incidental finding be managed? Epidemiological data show that the incidence of such contralateral asymptomatic hernias can be as high as 20%. The management strategy for these hernias has changed considerably over time. Although traditional "watchful waiting" was once widely adopted, long-term follow-up studies have demonstrated that approximately 70% of asymptomatic patients eventually require surgery due to symptom progression, and increasing age is associated with higher surgical risks. Consequently, with the widespread adoption of laparoscopic techniques, simultaneous repair of asymptomatic hernias during the initial surgery has become a common clinical choice. However, this decision raises a critical question: how can the surgeon balance the need to repair the existing anatomical defect against the risk of introducing new long-term complications from the intervention? This makes the choice of repair material particularly important. Currently, synthetic polypropylene meshes, with their proven effectiveness in reducing recurrence rates, are considered the gold standard for inguinal hernia repair. However, as permanent implants, they may be associated with long-term complications-chronic postoperative pain and foreign body sensation, which affect patients' long-term quality of life. Biologic meshes offer a different option. Derived from decellularized extracellular matrix, they are designed as temporary scaffolds that guide autologous tissue regeneration and ultimately degrade. Theoretically, this avoids a permanent foreign body reaction and may reduce long-term discomfort. Nevertheless, the clinical value of biologic meshes in inguinal hernia repair remains controversial. Some studies suggest that biologic meshes reduce chronic pain and improve quality of life; others show no difference in pain or recurrence rates compared with synthetic meshes. Meta-analyses have not demonstrated clear superiority of biologic over synthetic meshes in overall complications, recurrence, or chronic pain, and the heterogeneity among existing studies is high. The BIOLAP randomized clinical trial, published in JAMA Surgery in 2025, provided high-level evidence for symptomatic bilateral hernias. It showed that in laparoscopic inguinal hernia repair, biologic mesh did not significantly reduce postoperative pain. Moreover, it was associated with a significantly higher 2-year recurrence rate (11.2% vs. 2.5%) and a higher seroma rate (33.4% vs. 21.6%). However, a key question remains: can these conclusions be directly extrapolated to the setting of contralateral asymptomatic hernia repair, where the therapeutic goal is to maximize long term comfort rather than to relieve existing symptoms? The investigators previously conducted an exploratory single-center randomized controlled study (n=52, BiSOH) that addressed this question preliminarily. In that trial, the biologic mesh group had significantly lower inguinal pain scores at both 1 month and 6 months, with pain decreasing over time in both groups. Quality of life measured by SF-36 was significantly better in the biologic mesh group at both follow-up time points, and the EQ-5D score was higher at 6 months. These findings suggest that biologic mesh may offer advantages in chronic pain control and quality of life for occult hernia repair, contrasting with the BIOLAP conclusions. However, the single center design and methodological limitations prevented confirmation of the primary endpoint difference, highlighting the need for a multicenter, high-quality clinical trial. Currently, international guidelines lack high level evidence on the optimal mesh type for simultaneous repair of contralateral asymptomatic hernias. Therefore, this multicenter, randomized, single-blinded, parallel-controlled trial was designed to compare biologic versus synthetic meshes in this specific scenario. The hypothesis is that the use of a biologic mesh (porcine UBM/SIS composite) reduces chronic pain on the asymptomatic side at 6 months without increasing recurrence, compared with a synthetic mesh (self-gripping polyester). The biologic mesh is a porcine urinary bladder matrix and small intestinal submucosa composite (UBM/SIS) manufactured by ZR Medtech (Suzhou, China). It is a non-cross-linked, acellular, collagenous matrix produced through patented decellularization and antigen removal processes. It has been used for various soft tissue defect repairs.

The goal of this observational study is to learn about the effects of the timing of radiation therapy and immunotherapy in adults with non-small cell lung cancer (NSCLC) that has spread to the brain. The main questions it aims to answer are: 1. Does the timing of the two treatments change how long the brain tumor stays stable and how long participants live? 2. What medical problems do participants have when receiving these treatments at different times? 3. How does the timing of treatments affect the body's immune system? Researchers will compare participants who receive radiation and immunotherapy 30 days or less apart to those who receive them more than 30 days apart to see if the timing affects the treatment's success and safety. Participants already receiving radiation and immunotherapy as part of their regular medical care will: 1. Allow researchers to collect information about their treatment, health, and medical imaging during regular checkups. 2. Give a small blood sample during their routine blood draws. 3. Have standard magnetic resonance imaging (MRI) scans of their brain.

This prospective multicenter study will validate the model's accuracy in preoperative molecular subtyping and its value in prognostic assessment and clinical decision-making across multiple neurosurgical centers.

Abstract: Objective: This study aimed to investigate the effect of different bed angles (0° vs. 15°) on the incidence of intraoperative hypoxemia in patients undergoing gastroscopy and colonoscopy. A prospective randomized controlled trial was conducted to evaluate the impact of patient positioning on respiratory safety, providing evidence for individualized anesthesia management. Background: With the increasing popularity of painless gastrointestinal endoscopy, hypoxemia has become a major safety concern in anesthesia management, particularly in elderly and obese patients. Studies have shown that the incidence of hypoxemia can exceed 26%, highlighting the importance of optimizing respiratory safety during anesthesia. Methods: A total of 400 patients scheduled for painless gastrointestinal endoscopy were recruited and randomly assigned to a control group (0° left lateral position) or an experimental group (15° left lateral position). Baseline data were recorded preoperatively. Intraoperative vital signs were monitored, and the occurrence of hypoxemia and other complications was documented. Data were collected and processed in a blinded manner, followed by statistical analysis using SPSS 26.0.

Title: Effect of Tegileridine on Postoperative Bowel Function Recovery in Abdominal Surgery: A Multicenter, Randomized, Controlled Trial The goal of this clinical trial is to evaluate the effectiveness and safety of tegileridine, a biased μ-opioid receptor agonist, for patient-controlled intravenous analgesia (PCIA) after abdominal surgery. The main question it aims to answer is: Is tegileridine superior to morphine in promoting the recovery of gastrointestinal function within 72 hours after abdominal surgery? Researchers will compare the experimental group (receiving Fumarate Tegileridine Injection) to the active control group (receiving Morphine Hydrochloride Injection). Both groups will also receive dexmedetomidine in their PCIA pumps. This comparison will determine if tegileridine is more effective for bowel recovery and has a better safety profile. Participants who are scheduled for elective abdominal surgery under general anesthesia will: 1. Be randomly assigned to receive either a tegileridine-based or a morphine-based pain relief pump after surgery. 2. Use the patient-controlled analgesia (PCA) pump for up to 72 hours postoperatively to manage their pain. 3. Be assessed for the time it takes for their bowel function to return (tolerating food and having gas or bowel movement). 4. Have their pain levels, overall recovery quality, sleep quality, and any side effects monitored during hospitalization. 5. Be followed up 30 days after surgery.

Abstract Background Intravenous thrombolysis is the cornerstone of early treatment for acute ischemic stroke (AIS), but some still have a poor prognosis, especially in patients with mild disabling stroke. Tenecteplase (TNK), a novel thrombolytic agent with favorable pharmacokinetic profiles, and butylphthalide (NBP), a multi-targeted neuroprotective drug, have shown promising efficacy in separate clinical applications. However, evidence for their combined use in mild disabling AIS is lacking. Aim To determine whether TNK combined with NBP can improve functional outcomes compared with TNK monotherapy in patients with mild disabling AIS who receive thrombolysis within 4.5 hours of onset. Design BENEFIT-2 is a prospective, multicenter, randomized, double-blind, active-controlled trial. Eligible patients are randomized 1:1 to receive either TNK plus NBP (combination group) or TNK plus placebo (control group) via stratified block randomization. The combination group receives sequential NBP sodium chloride injection (25mg/100ml, twice daily for 7 days) and oral NBP soft capsules (0.2g, three times daily) until day 14; the control group receives matching placebos. Eligibility criteria include age 18-80 years, onset time ≤4.5 hours, NIHSS score 2-5 with disabling manifestations (hemianopia, aphasia, or limb weakness), and pre-stroke modified Rankin Scale (mRS) score ≤1. Study outcomes The primary outcome is the proportion of patients with mRS score 0-1 at 90±7 days. Secondary outcomes include changes in NIHSS score, recurrence of ischemic stroke, composite vascular events, quality of life (assessed by EQ-5D scale), and ischemic penumbra salvage rate. Safety outcomes include symptomatic intracranial hemorrhage (sICH), vascular death, all-cause death, and adverse events within 90 days. Discussion BENEFIT-2 is the first large-scale randomized trial to evaluate the synergistic effect of "vascular recanalization + neuroprotection" in mild disabling AIS. By combining TNK and NBP, this study aims to fill the evidence gap and provide a new therapeutic option to improve functional recovery in this specific population.

This study is being done to find a faster and more accurate way to tell whether the necrosis in patients with acute necrotizing pancreatitis (ANP) has become infected. In the absence of microbiological confirmation, clinicians often have to initiate empirical antibiotic therapy for suspected pancreatic infection-a practice supported by current guidelines but one that may contribute to antimicrobial resistance. In this study, the investigators will combine metagenomic next-generation sequencing (mNGS) which could improve the accuracy of infected pancreatic necrosis (IPN) diagnosis and host transcriptional response analysis which could discriminate infectious and noninfectious inflammatory syndromes. In a prospective, multicentre, cohort study, 200 consecutive patients ≥ 14 years with ANP will be enrolled at four tertiary hospitals from Novemeber 2025 to December 2026. If validated, this single-blood approach could enable early, pathogen-directed therapy, curtail unnecessary antibiotics and expedite surgical timing in ANP.

The number of atrial fibrillation (AF) patients in China is approximately 32.76 million, with a prevalence rate of 2.3%. AF is associated with severe outcomes such as stroke and heart failure. Metabolic disorders (e.g., obesity, diabetes mellitus, dyslipidemia) are closely linked to the onset and prognosis of AF. However, the epidemiological characteristics and disease burden of AF combined with metabolic disorders in China remain unclear. Additionally, the impact of complex multi-dimensional metabolic disorders on AF prognosis requires further investigation, and current clinical guidelines lack targeted management recommendations for this population.

The study is observational and involves no experimental interventions.

Xiangya Cardiopulmonary Health and Disease Cohort (XY-CPHDC) is a non-intervention study grounded in real-world data. It is designed as a bidrectional clinical cohort combined retrospective and prospective design, in order to evaluate cardiopulmonary function systematically and holistically, integrate physiology and medical theory, and explore the changing pattern of the cardiopulmonary under different health states. Cardiovascular System and Respiratory System are closely linked and interdependent physiological systems, and they play a vital role in maintaining normal life activities in the human body. Patients with cardiopulmonary disease often have conspicuous comorbidity characteristics, however, current measurements of cardiopulmonary function indicators are mostly limited to the assessments of single organ. This pattern of subspecialty care leads to deficiencies in the recognition of cardiopulmonary synergy dysfunction, and there is an urgent need for a more comprehensive and systematic approach to assessment. This study plans to construct a cardiopulmonary holistic assessment cohort, aiming at comprehensively and systematically reveal the intrinsic connection between the cardiopulmonary function in different scenarios, such as resting, exercise, and sleep, to deeply explore the core indicators of cardiopulmonary holistic function, to construct a joint stratification system of cardiopulmonary function, and to map cardiopulmonary comorbidity spectrum, so that they can accurately guide the diagnosis of the disease, the prognostic prediction and the intervention strategies.

Sleep disordered breathing (SDB) is one of the most common sleep disorders, including obstructive sleep apnea (OSA), central sleep apnea (CSA), sleep-related hypoventilation, hypoxemia, etc., with OSA being the most prevalent. Also, SDB shows high comorbidities with multisystem diseases. Furthermore, compared to patients with pure SDB, those comorbid with SDB and other disorders like cardiometabolic dysfunction and cognitive impairment experience poorer quality of life, higher rate of disease progression and mortality, and a greater economic burden. Currently, there are limited cohorts to study the associations between SDB and multisystem diseases. The aim of this study is to establish an ambispective clinical cohort for SDB in Xiangya hospital from central-south China (Xiangya Sleep Disordered Breathing Cohort, Xiangya SDB cohort) including retrospective part and prospective part, which covers multi-dimensional data of sleep monitoring, demographic, daily behaviors, clinical manifestations and comorbidities status, life quality, treatment information and evaluation, etc. by self-reported questionnaires and objective assessments and tests. Besides, whole peripheral blood is drawn for following biomarkers study and omics analysis. The main goal is to achieve precise management of SDB and related multimorbidity, containing to early identify risk individuals for multisystem impairment, significantly improve their prognosis and ultimately enhance overall health. In detail: first, to reveal how multisystem impairment related to SDB evolves; second, to identify which indicators closely involve system dysfunction due to SDB; third, to build an efficient model and a cost-effective platform to screen high-risk population and tract therapeutic effect.
